Title: Storage device, control method, and control device for storage device
Inventor: TONO YOSHINARI
IPC: G11B21/10
Filed: 2007-07-30
Abstract: <P>PROBLEM TO BE SOLVED: To surely prevent the deterioration of control accuracy during a seeking control even when a signal from an acceleration sensor contains parallel external disturbance vibration components, external noise, and noise generated by an SN ratio of the sensor itself.  <P>SOLUTION: A seeking control unit 50 moves a head near the target track of a storage medium under coarse control, and changes to fine control to position the head in the target track. A rotation external disturbance compensation control unit 60 adds rotation external disturbance vibration detection signals based on acceleration sensors 56-1 and 56-2 as compensation signals to the seeking control unit 50 to cancel the rotation external disturbance vibration components. A compensation control switching unit 62 sets the rotation external disturbance compensation control unit 60 to an ON or OFF state. When identifying a coarse seeking error outside a fine switching error range at the coarse control end time of the seeking control unit 50, the compensation control switching unit 62 switches the rotation external disturbance compensation control unit 60 to a reverse set state, thereby causing the seeking control unit 50 to perform seeking again.  <P>COPYRIGHT: (C)2009,JPO&INPIT
